COIN-OPERATED DEVICE FOR BICYCLE-PUMPS.

SPECIFICATION forming part of was meet No. 655,108, dated July 31, 1900.Application filed December '7, 1899- fierial No. 739,542. (No model!),To aZZ whom it may concern.- 7 Be it known that I, THOMAS PALMER,citizen of the United States, residing at Washington, in the District ofColumbia, have invented certain new and useful Improvements inCoin-Operated Devices for Bicycle-Pumps; and I do declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and tothe letters of reference part of this specification. i

This invention relates to new and useful improvements in slot-machines,and especially to an apparatus designed especially for use in connectionwith a bicycle-inflating pump, whereby it is necessary to drop a coininto the slot of the apparatus before a'certain valve is allowed toclose over the open end of a tube having communication with the cylinderof the pump, which causes the air to be forced through a passage-way, atthe end of which connection may be made with the inflatingvalve of thetire of the bicycle.

More specifically,the present/invention con sists in the provision of aslot-machine for use in connection with bicycle-inflating pumps in whichit is necessary before the apparatus can operate to drop acoin into aslot, which coin falls by gravity to a position covering an aperture inthe free end of a spring-actuated plate, which plate is designed toclose over theopen end of a pipe having communication with the interiorof the pump-cylinder,'a vertically-operating rod pivoted to theleverpipe on which the rim of the bicycle-wheel restswhile beinginflated being adapted to strike against said coin and depress with itsaid plate.

To these ends and to such others as the invention may pertain the sameconsists, further, in the novel construction, combination, andadaptation of the parts, as will be herein after more fully describedandthen specific ally defined in the appended claims. I My invention isclearly'illustrated-in the accompanying drawings, which, with theletters of reference marked thereon, form a part of thisapplicatiomandin which Figure'l is a side elevation of my slot-machine for operatingbicycle-pumps, the cas ing being shown in section. Fig. 2 is a centralvertical section through the apparatus. Fig. 3 is a sectional view online 3 3 of Fig. 2. Fig. 4' is a cross-sectional view onj'line 4 at ofFig. 1 Reference now being had to the details of the drawings by letter,A designates the easing of the apparatus, which is shown'only in sectionin the drawings. Located infthejcas ing is a' hand-operated air-pump B,with a a piston and plunger of ordinary construction. Leading from thelower end of the cylinder of thepump is a pipe 0, having connected'there to a union 0, to which union is connected at' right angles to thepipe 0 a vertical pipe D, with its upper end normally open. This pipe D,as shown in Fig. 2, passes through thebottom of the box E, provided toreceive the coins which have been dropped in the slot for the purpose ofmaking it possible to use the pump. Connected to the opposite end of theunion 0 is a'pipe G which in turn is connected to an elbow C from whichrisesa vertical pipe G with an open upper end.. For supporting the upperend of said pipeC, I have shown a screw-eye 0 Fig. 1, which isfastened'to the frame of the apparatus.

Mounted on theupper end of the post F is an apertured plate G, held bymeans of nuts G to said post. Pivoted to the plate Gis a second plate H,which'has sec'ured'to its" under surface a rubber valve H, designed whensaid plate H is depressed to close over the upper end of the pipe D andprevent theescape of any air through said pipe D. A spring I, bearingbetween the adj usting-nut LFand the undersurfaceof the valve H, servesto throw the plate H up, so that the valve H- will normally clear theupperend of the vertical pipe D, in which position the apparatus wouldbe inoperative. On the upper surface of the plate H is a hopper J, theupper face of the plate forming the bottom of the hopper, and directlyover said hopper is the outlet end of the chute K, having an opening K,through which the coin, which is dropped into the upper end of thechute, falls by gravity onto the upper surface of the plate H and intothe position shown in Fig. 2, coveringtheaperture h, the coinbeingdesignatedin said fig ure by letter N. One side of the hopper,which receivesthe coins, is cut away and has adown' wardly-disposedslide H, Fig. 1 of the draw ings, down which the coins slide into therenormally at its highest limit by means of the spring P, Fig. 1,whichbears between the cross-piece of the apparatus and the lug 0carried by the lever O. Pivoted to the lever O at Q is a short socketmember Q, the lower end of which is internally threaded to receive theupper endoof the rod B, the lower end of which passes between the platesq and -nor-' mally, when depressed by the lowering of the i leverO,adaptedto pass through the. aperture h in the plate H. Mounted on.a pinL,

carried between the plates q, is a lever'L,

the lower end of which is connected to a spring L which spring is inturn fastened to an apertured plate L carried overthe pipe D and heldbetween the two nuts L the office of this spring L being to normallyhold the lower end of the lever L against the free end ofthe pivotedplate H or against the edge of the coin N, which may project a slightdistance beyond the edge of the plate H when the rod R is forced down onthe upper face of sa d co [A portion of and-mounted on saidthreads aretwo adj usting-nuts r, between which is held a plate of rectangularshape R which is longitudinally slotted to receive the upper free end ofthe lever L. lhe upper end of the lever L is laterally bent, as at L andslotted, as at L, and to the walls of said slotted portion is held a pinZ, on which is mounted a dog Z, which is normally held in the positionshown inF-ig. 2 by means of the spring 1*. This spring has one endsecured to the upper end of the lever L and is bent forward, with itsfree end bearing against the upper edge of said 'dog at a positionslightly behind its pivotal point. As the plate R is depressed theunderside of the latter near its outer end'strikes against the upperedge of the dog near-.itsouter end and the latter tilts idly, and afterthe plate R has passed below the dogthe latter is returned to its normalor horizontal position under the action of the spring Z When the plate Rreturns to its normal or highest position, the upper edge of said'platestrikes against the under side of said dog near the outer end of thelatter. As the dog begins to tilt its rear end on the under side willstrikeagainst the bevel surface forcibly against the edge of the coinwhich has been previouslydropped downthe chute and rests over theaperture h in the end of the hopper J and kick against said 'coin withsuffithe rod R is threaded, as at r,-

oient force to knock it. out oifthe hopper, causing said coin to slidedown the inclined way and into the receiving-box beneath.

The outer end of the lever O is preferably rounded and hasa central boreQ which terminates at a point opposite the upper end of the pipe 0Leading into and communicating with the bore Q at its inner end is anipple Q about which is a rubber cushion Q which abuts against the upperend of the pipe C? as the nipple ente-rs the bore of said pipe; Theweight of the wheel resting on the outer end of the lever'O will exertasufficient pressure on'the cushion Q, so as to make an air-tight joint.

Near the outer end of the rod 0 and seated in a recess at right anglesto the bore Q Fig.

4, is a nipple Q", Which is surrounded by a rubber cushion Q On oppositesides'of the cushion Q are the curved plates Q held to the bar 0 bymeans of suitable screws, as shown,.these plates being provided for thepurpose of holding the upper end-of said nipplc and cushion securely.

In operation a coin is firstplaced in the chute K. The saidcoin,.falling by gravity, will stop in, the position shown in Fig. 2, inwhich position the coin rests over the aperture h. The rim of the wheel,the tire of which is placed over the end'of the lever 0, causes saidlever to be depressed, and with it the rod R, which strikes againsttheupper surface of the coin and depresses the pivoted plate H downwarda sufficient distance so that the valve H will close over the upper endof the pipe D. When the valve H is in its seated position, the nipple Qis positioned in the bore at the upper end of the pipe (3, and thecushion Q bears air-tight against the upper end of said pipe, and theair-passage 'from the pump to the tire is uninterrupted.

The in flatin g-valve of the tire is held over the nipple Q before thepump is operated by hand. When the tirehas been inflated and the wheelremoved from the end'of the lever O, the spring P will cause the lever Oto resume its normal position, which is at its highest throw. On thereturn upward'movement of the plate R its outer upper edge strikesagainst the under side of the outer portion of the dog, and the lever L"will be caused to tilt, its lower end being thrown out a sufficientdistanceto allow the plate R to pass the dog Z, after which the springL?will fluence of thespring L'return to its normal position and the valveH will be unseated.

In case it is attempted to inflate the tire without first dropping acoin in the chute the result wilLbe that the lower end of the rod R willpass through theaperture h and the pivoted plate H will remain idle, andconsequently the valve carried thereby will remain unseated. The leverL, it is true, is actuated at each depression of the rod R and kicksagainst the end of the pivoted plate, but accomplishes no result unlessa coin has been previously dropped into the chute.

It will be observed upon reference to the drawings that in order to makethe piston of the handpump operate easily I provide a valve in the lowerend of the cylinder of the pump, said valve resting in a suitable cup orsocket, and as the piston is raised the air is allowed to enter anaperture, which is closed.

by the valve as the piston is pushed down.

Having thus described my invention, what I claim to be new, and desireto secure by Letters Patent, is-

1. A coin-operated apparatus for bicyclepumps comprising in combinationwith an airepump, open-ended pipes communicating With the cylinder ofthe pump, a pivoted lever having a bore in one end, a nipple leadinginto said bore, adapted when said lever is depressed, to communicatewith one of said open-ended pipes,-and means for closing the open end ofthe second pipe communicating with the air-pump, as said lever isdepressed.

2. A coin-operated apparatus for bicyclepumps, comprising in combinationwith the pump, open-ended pipes communicating with the pump-cylinder, alever pivoted to a suitable support, and having a bore in its outer end,a nipple leading into and communicating with said bore, and'positionedopposite the upper end of one of said open-ended pipes,

a pivoted plate carrying a valve, and means for seating said valve asthe lever is depressed, as set forth.

3. A coin-operated apparatus for bicyclepumps, comprising in combinationwith the pump, open-ended pipes communicating with the cylinder of thepump, a pivoted lever hav- I pivoted plate and in the path of said rod,to depress said plate and means for removing the coin fromsaid plate, asset forth.

4. A coin-controlled apparatus for bicyclepumps, comprising incombination with the pump, the open-ended pipes communicating with thecylinder of the pump, a pivoted 1ever having a bore in one end a nippleleadinginto and communicating with theinner end of said bore, saidnipple being positioned opposite the end of one of said open-endedpipes, a pivoted plate spring-actuated and having a valve on its undersurface adapted to be seated over theupper end of the second of saidopen-ended pipes, a rod pivoted to said lever, the lower end of said roddesigned V to strike against a coin, that has been previously depositednear the free end of said pivoted plate, whereby the latter is depressedand the valve carried thereby seated, and a sprin -actuated leverdesigned to kick the coin off from said plate, as the rod is raised,

as set forth.
